| Abstract: | The determination of trace Mercury in water by electorlytic proconcentration and graphite furnace atomic absorption spectrophotometry is described.Ten parallel determinations of 100ml of Solution Containing 0.6ng/ml Hg(11) give relative standard deviation 4.1%, the detection limit 0.1ng/ml, More than 10 coexisted ions do not interfere in determination. |
